common: check if a given rename flag is supported in _require_renameat2

Browse Source 
Some testcases may require a special rename flag, such as
RENAME_WHITEOUT, so add support check for if a given rename flag is
supported in _require_renameat2.

[Eryu: rename the helper to _require_renameat2 while we're at it,
and add 'exchange' check to generic/398 and generic/419]
